Description
Technical field
The utility model relates to a kind of resistance test technical field, specifically, relates to a kind of four point probe resistance test pen.
Background technology
Along with the development of lithium ion photovoltaic industry is rapid, the output of monocrystalline silicon also increases day by day, and wherein, having the call of monocrystal rod, requires also higher to its resistive performance.Monocrystal rod is come out of the stove after cooling, will measure accurately its resistance.In daily production, require the resistance measuring its point in surface every 100mm.And use is exactly four point probe resistance meter the most frequently, it is made up of test pen, connecting line and computer display screen, and what its test probe adopted is high speed draw point, has retractor device after probe.In use, after probes touch to testee surface, firmly press test pen, four probes just contact well with body surface, after data stabilization in LCDs, read data.Monocrystal rod smooth surface, and be curved surface, in the process using test instrument probe; probe often ruptures due to unbalance stress and slip; and the workload of test is large, it is many that this makes the difficulty of relay testing instrument turn increase, thus cause test instrument probe short for serviceable life.
For the problem that correlation technique middle probe tester serviceable life is short, at present effective solution is not yet proposed.
Utility model content
For the problem that prior art middle probe tester serviceable life is short, the utility model provides a kind of four point probe resistance test pen, with the probe of protective resistance tester, increases its serviceable life, thus reduces its use cost.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of four point probe resistance test pen, comprise test pen and protective sleeve that front end is provided with probe, wherein, the front end of described protective sleeve is provided with protection head, and on this protection head, the position corresponding with described probe is provided with probe mouth; The inside of described protective sleeve is provided with spring, is placed with described test pen in the endoporus of this spring, and position corresponding with the end of described spring on described test pen is provided with spring base; The rear end of described protective sleeve is provided with the block corresponding with described spring base.
Further, the material of described protection head is rubber.
Further, the shape of described protection head and the shape of tested monocrystalline silicon suitable.
Further, described protection head is arc.
The beneficial effects of the utility model are: by being provided with the four point probe resistance test pen of protective sleeve, and the shape of the protection head shapes of protective sleeve and tested monocrystalline silicon is suitable, make protective sleeve and monocrystal rod surface good fit, ensure that test pen can not double swerve, using the interval of test pen, protective sleeve also serves protective effect, ensure that external object does not directly contact with probe, and when test pen colliding surface or other objects, the spring in head and protective sleeve is protected to serve buffer action, avoid test pen impaired, thus increase the serviceable life of test instrument probe.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to be only embodiments more of the present utility model to the accompanying drawing used required in embodiment below, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
As Figure 1-3, the four point probe resistance test pen of the utility model embodiment, comprises test pen 4 and protective sleeve 5 that front end is provided with probe 3, wherein, the front end of described protective sleeve 5 is provided with protection 6, and in this protection 6, the position corresponding with described probe 3 is provided with probe mouth; The inside of described protective sleeve 5 is provided with spring 2, is placed with described test pen 4 in the endoporus of this spring 2, and position corresponding with the end of described spring 2 on described test pen 4 is provided with spring base 7; The rear end of described protective sleeve 5 is provided with the block 1 corresponding with described spring base 5.
In addition, in one embodiment, the shape of described protection 6 and the shape of tested monocrystalline silicon suitable, preferably, described protection 6 is arc.
In such scheme, for protection 6, the material of described protection 6 is rubber.
The beneficial effects of the utility model are: by being provided with the four point probe resistance test pen of protective sleeve 5, and the shape of the protection of protective sleeve 56 shape and tested monocrystalline silicon is suitable, make protective sleeve 5 and monocrystal rod surface good fit, ensure that test pen 4 can not double swerve, using the interval of test pen 4, protective sleeve 5 also serves protective effect, ensure that external object does not directly contact with probe 3, and when test pen 4 colliding surface or other objects, spring 2 in protection 6 and protective sleeve 5 serves buffer action, avoid test pen 4 impaired, thus increase the serviceable life of test instrument probe.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
